Shades of Hyperbolicity for Hamiltonians
M. Bessa, J. Rocha, M. J. Torres
We prove that a C2 Hamiltonian system H in M is globally hyperbolic if any of the following statements holds: H is robustly topologically stable; H is stably shadowable; H is stabl…
Extreme value statistics for dynamical systems with noise
Davide Faranda, Jorge Milhazes Freitas, Valerio Lucarini +2
We study the distribution of maxima (Extreme Value Statistics) for sequences of observables computed along orbits generated by random transformations. The underlying, deterministic…
Laws of rare events for deterministic and random dynamical systems
Hale Aytaç, Jorge Milhazes Freitas, Sandro Vaienti
The object of this paper is twofold. From one side we study the dichotomy, in terms of the Extremal Index of the possible Extreme Value Laws, when the rare events are centred aroun…
The compound Poisson limit ruling periodic extreme behaviour of non-uniformly hyperbolic dynamics
Ana Cristina Moreira Freitas, Jorge Milhazes Freitas, Mike Todd
We prove that the distributional limit of the normalised number of returns to small neighbourhoods of periodic points of non-uniformly hyperbolic dynamical systems is compound Pois…
Global Dynamics for Symmetric Planar Maps
B. Alarcon, S. B. S. D. Castro, I. S. Labouriau
We consider sufficient conditions to determine the global dynamics for equivariant maps of the plane with a unique fixed point which is also hyperbolic. When the map is equivariant…
